개요

Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan polymer produced industrially by Streptococcus zooepidemicus fermentation, replacing the original extraction from rooster combs. HA can hold up to 1,000 times its weight in water, making it the most effective biological moisturizer known. Applications span cosmetic serums and fillers, ophthalmic surgery (viscoelastic), orthopedic injections (viscosupplementation), and wound healing. Different molecular weights serve different functions — high MW for surface hydration, low MW for deeper skin penetration.

화학 공정

Streptococcus zooepidemicus is fermented aerobically on glucose at 37 degrees C for 18-24 hours in a controlled bioreactor with pH maintained at 7.0-7.5. HA is secreted into the broth at concentrations of 3-7 g/L. The broth is heat-killed, filtered to remove cells, and HA is precipitated with ethanol or isopropanol. The precipitate is redissolved, filtered through activated carbon, and re-precipitated to achieve pharmaceutical or cosmetic grade.

nUDP-GlcUA + nUDP-GlcNAc →[HA synthase] (GlcUA-GlcNAc)ₙ + 2nUDP (biosynthesis from nucleotide sugar precursors by HA synthase enzyme)
Glucose →[glycolysis + PPP] UDP-GlcUA + UDP-GlcNAc (metabolic precursor synthesis)

원자재

  • Glucose (C₆H₁₂O₆) — Corn starch hydrolysis (Carbon source)
  • Streptococcus zooepidemicus — Culture collection (non-pathogenic strain) (HA-producing organism)
  • Ethanol or isopropanol — Fermentation or petrochemical (Precipitation solvent)

최종 제품

  • Hyaluronic acid sodium salt — Cosmetic serums, dermal fillers, eye surgery, joint injections (MW range: 5 kDa (low MW) to 2,000+ kDa (high MW))

Environmental Impact

Bacterial fermentation is significantly more sustainable than rooster comb extraction, which required slaughterhouse byproducts and extensive chemical processing. The fermentation process generates modest organic waste. Ethanol used in precipitation is recovered and recycled. Overall environmental footprint is low due to the small production volumes.

안전 고려사항

최근 혁신

Recombinant Bacillus subtilis expressing HA synthase produces HA without pathogenic organism concerns.
Enzymatic degradation using hyaluronidase creates precisely controlled low-MW fragments for different applications.
Cross-linked HA hydrogels for dermal fillers last 6-18 months versus hours for unmodified HA.
